The CAS Registry Mumber 1769-50-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 9 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1769-50: (6*1)+(5*7)+(4*6)+(3*9)+(2*5)+(1*0)=102 102 % 10 = 2 So 1769-50-2 is a valid CAS Registry Number.
